IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 106,478, dated August16,1870. I

.t'o all whom it may concern.-

Be it known that I, JULIUs GERBER, of Rockford, in the county ofWinnebago and State of Illinois, have invented a new and usefulImprovement in Cultivators; and I do hereby declare that the followingis afull and exact description of the same, reference being bad to theaccompnnyingdrawings, and to the letters of reference marked thereon.

This invention consists of a device for connecting" the shovel standardto the cultivatorbeam, which is so constructed as to permit the verticaland lateral adjustment of the standards when desired. The details ofconstruction will be fully described hereinafter.

, Figure 1 represents a perspective view of the beam and standards, andFig. 2 top view of the bolt and standard'iron.

To enable others skilled in the art to make and use myinvention, I willnow proceed to describe fully its construction and operation.

A represents the cultivator-beam; and B,'the standard, provided with theusual shovel, b.

0 represents an angle-iron the vertical face of which is drawn closelyagainst the beam by means of the bolt 0, which secures it. Itshorizontal face is provided with notches or teeth, as shown.

d represents a clevis-shaped iron, provided with a bar, d, and suitablenuts, and having alsoattaehed an ear, W, the lower face of which latteris notched to correspond with the dpper face of the angle-iron o. Bymeans of theiron d the standard B is held, as shown. The

notched faces of the beam-iron and standardiron are secured to eachother bya suitable setscrew, e.

Theoperation is as follows: The standard is adjusted vertically byloosening the nuts on the standard-iron and moving it up or down, as maybe desired. The lateral adjustment of the standard is secured byloosening the setscrew 6, and by moving the face of the car 61 upon theface of the iron 0 until the desired position is obtained. The parts maythen be secured in this position by tightening the setscrew.

The construction herein described possesses all the advantages found inthe most a pproved form of fastening devices. The parts are all simplein themselves, and the desired adjustments are quickly and easily made.

Having thus fully described my invention, what I claim as new, and'desire to secure by Letters Patent, is-

The device described, consisting of the clevis d, with bar (1 andnotched face (1 angle-iron c, with bolt 0 and set-screw 0, when combinedand arranged as described, and employed in connection with acultivator-beam and shovelstandard, as described.
